Abstract :
A comparison of an analog and a digital controller driven 70 W two-stage power factor corrector converter is presented. Both controllers are operated in average current-mode-control for the PFC and peak current control for the DC-DC converter. Digital controller design and converter modeling is described. Results show that digital control can compete with the analog one in efficiency, PFC and THD.
